2018 AUDI A3 SEDAN octane

Checking and Filling
Checking and Filling Fuel
Gasoline grade
A pp lies to: ve hicles w ith gasoline engines
The correct gasoline grade is stated on the inside
of the fuel filler door .
The vehicle is equipped with a catalytic converter
and must only be driven with
unleaded gasoline .
Audi recommends using TOP TIER Detergent Gas­
oline. Additional information on TOP TIER Deter­
gent Gasoline can be found on the official web­
site (www .toptiergas.com).
The individual gasoline grades are differentiated
by
octane ratings. This value is given with (R +M)/
2 equating to AKI or in RON.
The following headings match the corresponding
sticker in the fuel filler door .
UNLEADED FUEL ONLY MIN. (R+M)/2 87
Regular/ MIN. RON 91 Regular
Use regular gasoline with minimum 87 AKI/
91 RON
i::>@ .
The max imum eng ine power is only reached if
p rem ium gasol ine 91 AKI/ 95 RON is used.
UNLEADED FUEL ONLY PREMIUM MIN. (R
+M)/2 91 / SUPER MIN. RON 95
Using premium gaso line with minimum 91 AKI/
95 RON is recommended.
If premium gasoline is not available, you can also use regular gasoline 87 AKI/ 91 RON . However
this does reduce th e engine powe r slight ly.
0 Note
- Fillin g the tank just one time with leaded
fuel or other metallic additives will cause
permanent deter iorat ion to the catalytic
converter function.
- When gasoline with an octane rat ing that is
too low is used , h igh speeds or heavy engine
load can lead to engine damage.

(D Tips
The vehicle may be filled with fuel that has a
h igher octane rating than what is required by
the eng ine.
Blended gasoline
App lies to : vehicles wi th gaso line e ngi ne
Use of gasoline containing alcohol or MTBE
(methyl tertiary butyl ether)
You may use unleaded gasoline blended with al ­
cohol or MTBE (commonly referred to as oxygen­
ates) if the blended mixture meets the following
criteria:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
- Anti-knock index must be 87 AKI or h igher.
- Blend must contain no more than
3% metha-
nol.
- Blend must contain more than
2% co-solvents.
Blend of gasoline and ethanol (grain alcohol or
ethyl alcohol)
-Anti-knock index must be 87 AK I or h igher.
- Blend must not conta in more than 15% etha-
nol.
Blend of gasoline and MTBE
- Anti -knock index must be 87 AKI or higher.
- Blend must not contain more than 15% MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform es­
pecially well for winter or summer dr iv ing . Dur­
i ng seasonal change-over, we suggest that you
fill up at busy gas stat ions where the seasonal
adjustment is more lik ely to be made in t ime.
@ Note
- Methanol fuels which do not meet these re­
quirements may cause corrosion and dam­
age to plastic and rubber components in the
fuel system.
- Do not u se fue ls that fail to meet the speci-
fied criteria in this chapter.
